After disabling the defense turret in an asteroid belt it remains there at 0%, indestructible. This causes issues with the NPC AI in the following fighter skirmish. Since the turret is technically still in sector and "hostile", NPCs will target and shoot the disabled turret allowing themselves to be mowed down by enemy NPCs.

EDIT:

Could disabled turrets be made neutral or something that prevents them from showing up on target nearest hostile? Was kinda awkward not being able to use nearest hostile half the time.
